Yokomo BD-301RF1 Blue Anodized Front Mount for BD7/BD5 41.3mm Pitch  [BD-301RF1]

Touring car front arm mounting component

This component is Yokomo model BD-301RF1, a front suspension arm mount produced in blue anodized aluminum. It is intended as an upgrade or replacement part for BD7 and BD5 touring chassis, with a left-to-right suspension arm pin pitch of 41.3mm that you should match when selecting replacement parts.

The mount functions as a stiff attachment point for the front suspension arms, affecting how the front end resists roll and reacts to steering inputs and surface changes. In tuning setups it is used to tweak roll centre and front bite by combining different arm configurations, hinge-pin placements, and damper settings while keeping the stock chassis unchanged.

Installation guidance: verify the 41.3mm pin spacing lines up with your existing hinge pins prior to fitting, inspect for potential contact with steering links and shock towers, and tighten fasteners to conventional RC hobby torque standards. Confirm fit on the bench before track use.
